The Ubiquitous ESRI Patch Update
Well, that didn’t take terribly long. ESRI has released service pack 1 for ArcGIS 9.1 (Desktop, Engine, Server, SDE, and ArcIMS). To answer your next question, no, it did not fix the bug you were interested in. It fixed all of the other bugs everybody else was interested in. But the fix list is pretty long, so you should probably install it anyway. You can find it and other patches at http://support.esri.com/.
